You may have noticed that we were taking a 30 day break from GSH to get some answers. Well, we got the answers and it is so clear to us that GSH is so necessary for people with CF. Our daughter lost weight and her stools became a mess toward the end of the 30 days. We are working to get her back on GSH, slowly, but are anxious because her appetite had dropped off towards the end as well. This is just another example of how beneficial this medicine is.
